Long ncRNA uc.173 has recently been indicated as a promotor of regeneration of the intestinal mucosa. The epithelium of the intestinal mucosa is a rapidly self-renewing tissue in the body, but the renewal process is often defective due to various diseases. However, the exact underlying mechanism remains unknown. Here, we investigated the role of the PC/ISC niche in uc.173-reguated intestinal mucosal growth and further investigated mitochondrial metabolism in this process
